Since I put the XXR's on my car I decided to put my 17" Bronze Abarth wheels on my wife's Espresso Brown 500 Sport.
Once I get my Vogtland springs all on the Abarth, I might have to put Abarth springs on her car too.

Did she have 16's and if so how do you adjust for the different size wheel to make sure the speedo is correct?

She had 16's but the tires were 205x45, the 17's are 205x40. @70 MPH it should only be about .6 mph difference according to the tire comparison site.
So I will drive by the speedo and not sweat it.

The reason I asked is my Abarth has 16's and eventually I want to put 17's on it. I was hoping there might be a way to go into some area and adjust the tire size setting. I wonder how they do it from the factory?

If you go to the website for discount tire and then to the area "speedometer accuracy" it has a link to a calculator where you can see what the change in tire size does to the accuracy of the speedometer readout.

I'm sure there is a setting in one of the car's computers. I have no idea if a dealership can change that parameter or not.

Not sure about the Fiats but, I tried to get my 2014 Dodge Dart computer recalculated for larger tires and was told it couldn't be done.
They both use a lot of the same parts.
